2 Claims. v

removal of some or part' of theleaves withoutY destroying the effect or appearance of the book and which further permits, offtlieA addition of leaves to the unitary. set'.

A' further object oi `the invention is toprovidev a book cover and' ller `member of suchcharacter and construction Ithat the same may. be

readily assembledin book form to produce ,aneat and attractive appearance, andyet which` may be quickly andeasily separated from one another for the purposes abovestated withoutthe exercise ofspecial skill, toolsor.- implements.

With these objects in view, ,together withothers which willappear as the description proceeds, the` inventionconsistsin y,the novel construction, combination and'arrangement of parts, all as will be described more fully hereinafter,'illustrated in the drawing, and particularly pointed out in the claims.

In the drawing:

. Figure 1 is a perspective view of a book constructed in accordance with the invention, the locking key being shown removed therefrom,

Figure 2 is an enlarged fragmentary sectional view taken through the back of the book and illustrating the assemblage of parts,

Figure 3 is a similar View taken longitudinally through the book back,

Figure 4 is a view similar to Fig. 3 and illustrating a modified form of the invention.-

As has been heretofore stated, the structure of my invention is directed to a book of that nature wherein the binder or cover and the I'lller may be easily assembled or taken apart, the invention being directed particularly to books to contain samples of cloth, paper or other materials of the same` general nature. It is my purpose to provide a binder or cover of attractive appearance for the accommodation of ller leaves or sheets of samples to be displayed, and wherein these samples may be readily removed from the iiller member when desired, or replaced by other samples; without impairing the appearance of thebook and without aifectingits operation.. It frequently becomes necessary to `removeor.` replace one or more sheets. of a `sample-ibook, and with equipment heretofore. proposedthis-has been difficult if notl impossible. of accomplishment without destroying the appearancefof thesample book or without the exercise ofspecial skill or equipment; Thebook of. my. inventionentirely overcomes such objections, andthe detailed'construction will now be set forth, referencebeing had to.the accompanying drawing. I,

The binder or cover of the;bookincludes-front and` back leaves or boards and lhingedlyiconnected tothe back member indicated atl. The back member. is` preferablyfof channelmetal of lightgaugeand may assume "U shape in cross section. as-shownv .This back is provided with-a bottom.8of similar metal/permanently secured. within. the .bottom in spaced relation .to therlatter by any approvedtmeans.` In the present instance this bottomilhas upstandingxportions 9` at its longitudinal `edgeszwl'iich maybe riveted or spot.' weldedztofthe sideslof, the-back 1, anditi willbe understoodl thatI this i bottom is i coextensive with the back. Theirontzand backboards-E,` aswellas` the ,.back:1; `may, Ibef covered. with cloth or vother material to add to the attractive appearance of the completed structure, such material affording means whereby the boards 5 and are hingedly connected to the sides of the bottom 1.

The bottom 8 forms an open channel lengthwise of the back of the book, and Within which the removable filler unit is secured. This unit includes a clip I0 of narrow gauge metal the base portion II of which is of substantially equal breadth with the channel formed by the bottom 8. The clip I0 is also coextensive with or posslbly a trifle shorter than the length of the book back. This clip is provided with upstanding resilient jaws I2, each of which provides a shoulder I3 near its juncture with the base of the clip. The jaws I2 rise from the sides of the clip in spaced parallel relation, and the metal of which the jaws are formed is such as to exert gripping pressure upon a filler or packet of leaves I4 ofl cloth, paper or other material arranged between said jaws. The leaves I4 are preferably, though not necessarily, secured as by gluing or cementing to a plate I5 of a length equal to that of the clip and of a breadthto restupon thebottom I I of the clip between and beneath the shoulders I3 of the jaws. This arrangement permits the body or unit of filler leaves to be slid and maintained evenly within the clip I0.

After the leaves have been inserted between the jaws I2 of the clip, the latter may be pressed toward each other so as to frictionally grip between them the body of leaves. Any preferred tool or instrumentality may be employed for this purpose, and it will be obvious that the leaves may thus be firmly bound or secured within the clip and that the latter with the leaves form a substantially unitary structure.

The means, in one form of the invention, for detachably securing the clip and its associated body of leaves within the back includes a hook member I 6 depending from the base Il of the clip near one end thereof to engage within an opening II in the bottom 8, and an apertured detent or loop I8 projecting from the base II of the clip near its opposite end. This detent projects through an opening I9 also formed in the bottom 8 and near one end thereof. A key 20 having a spring prong or finger 2| is inserted in one end of the book back with the prong engaged in the aperture of the detent I8 whereupon the filler unit is maintained secure in the back. 'Ihe key 20 is provided at one end with an integral pad 22 conforming to the size and shape of the end of the book back, and preferably this pad is covered with fabric or cloth conforming to the covering of the front and back boards. The prong 2| has a spring portion as shown to bind against the bottom 8 and to hold the prong frictionally against accidental withdrawal or displacement.

Figure 4 of the drawing shows a modified form of the invention, wherein the prong I6 is disposed of and both ends of the clip are secured in the backing by means of removable keys 20 having their spring ngers 2| engaged in openings in lugs or detents` I8. In other Words, the removable key arrangement at'one end of the book, as shown in the preferred form, is duplicated at the opposite end of the back. This arrangement may provide a more secure seating of the removable clip, and minimizes the difficulty of making the insertion that might present itself should lug I6 become bent or distorted.

From the foregoing it is apparent that a book constructed in accordance with this disclosure is capable of accomplishing the various desired purposes. The sample leaves I4 are cut in such size and shape as to fit evenly and smoothly within the covers. Adhesive along the inner edges of these leaves secures the same to the plate I5, whereupon the latter is inserted by longitudinal movement within the clip and below the shoulders I3. This insertion will be performed, however, with the jaws I2 spread apart, whereupon the said jaws are moved inwardly into secure clamping relationship with the pad or packet of leaves I4. The unit thus formed is readily inserted within the back and is held therein by the key in the manner described. Should it be desired to remove comparatively few of the leaves, it is but necessary to tear them along the edges of the jaws I2 without destroying the appearance of the book. When a number of leaves are to be removed, it may be found desirable to detach the filler unit and open one or both of the jaws whereupon the removal may be facilitated. The jaws may then be reset to firmly grip the remaining leaves between them and the unit replaced within the backing'. It will be understood that additional leaves may be added as desired, in the same manner.

Having thus described my invention, what I claim as new and useful is:

1. In a book, a binder, a clip including a base and parallel resilient jaws projecting upwardly from the edges thereof, shoulders on adjacent faces of said jaws near the lower ends thereof, a plate engageable in said clip and snugly fitting therein below said shoulders. leaves carried by said plate and adapted to be frictionally held between said jaws and means to secure said clip in the back of said binder.

2. In a book, a binder, a back for said binder, a bottom in said back, said bottom having openings therein near its ends, a clip to seat upon said bottom, a pair of loop members projecting from said clip` and adapted to extend through said openings, and spring lingers insertible in the ends of said book beneath said bottom to engage in said loops to retain the clip locked upon said bottom.
